The Browser Blocker Plugin puts the power in your hands to control what browsers(versions) can access your website content and which ones cannot. For the browsers(versions) that you block, the user has control over the splash screen that their clients receive. There is a "simple" mode for those who just want to block some browsers with the default settings, and there is an "advanced" mode for those who want to have a little more control over what is displayed to their clients.
